These boat lights are easily installed by the owner and are perfect for adding underwater lights to any watercraft without having to drill holes. They fit into the watercraft's current 1/2in NPT drain plug and can also fit "non-standard" drain plug sizes with an adapter.  

Step 1- Remove 1/2in drain plug "nut"

Step 2- Lubricate new light threads with anti-cease/corrosion grease

Step 3- Route the 18in wire attached to the light through 1/2in garboard drain hole

Step 4- Connect 18ft extension wire to the 18in light wire via the waterproof connectors inside the bilge/hull

Step 5- While leaving enough "slack" in the wire to pull approximately 20in out of the exterior drain hole, secure the remaining wire with zip ties every couple of feet until the nearest battery or switch. This will allow you to pull enough wire out of the exterior hole to disconnect the light if desired.

Step 6- Attach the 2 lead wire to a 10amp fused switch (recommended) or simply run directly to a battery while using the included fuse. A separate deep cell house battery is recommended as this light will draw 5amps per hour.  Do NOT connect to your boat only starting battery. 

Step 7- Enjoy the light every night for years to come. 

These lights are over twice as bright as other similar lights on the market.  Most other plug lights are only 27 watts and use cheap LEDs.  IllumiSea drain plug lights are a full 60 watts and use ultra-bright CREE LEDs.  More wattage + Premium LEDs = Much brighter Light guaranteed. 

Being based out of Virginia Beach, we designed these lights to be bright enough for the dirty summer waters of the Chesapeake Bay. 

These premium quality lights are designed to last in the harsh marine environment.  There are many cheaper lights on the market that don't even last one season and have and a brightness level that is quite a disappointment. 

A few other major differences:

• Designed with a higher wattage which makes it over twice as bright as the competition. Most other drain plug lights are 27w or less.

• It doesn't require an expensive electrician or mechanic to install.  Remove your drain plug and screw in your new light, wire to a switch or battery and enjoy.

• Includes a 3yr warranty & 30-day guarantee

• Includes worry-free overheat protected LED driver inside the light. Rest assured your light will last for many years in fresh or saltwater.

• 18in cord on the light that keeps it out of the bilge water plus an 18ft cord extension to run to a switch or battery.  Both include waterproof quick connects allowing for easy removal.

• Top-quality stainless steel IP68 waterproof housing with 12 extremely bright and efficient CREE LEDs.

It sounds off, but 1/2in NPT does not actually measure 1/2in, it measures closer to 3/4in.

Most of today's boats are manufacture with 1/2in NPT garboard drains.  There are a few models that have a larger 3/4in or 1in drains.  Our lights can still be used with other sized drains with a simple adapter. Some are available from IllumiSea. 

If you have an expandable 1in drain plug then the easiest method would be to install a 1/2 stainless or brass garboard drain.  With 3 simple screws, you will be up and running. 

• Make sure not to operate the light out of the water.  Even though the light has overheat protection, water is required to properly cool the light.

• Do not overtighten the light into the drain.  Tightening with a wrench it typically not required. 

• Use an anti-seize/corrosion grease that prevents the light and threads from the harsh marine environment.  Tef-gel or similar quality gel is recommended. 

We are a family owned and operated business that specializes in creating memorable experiences through our innovative line of aquatic lights. Founded by a Special Operations Combat Veteran and his wife in 2017, IllumiSea came to fruition on a fall evening while fishing with our 4 sons.

Being a family who loves to fish we purchased an underwater light for our dock. Our 6-year-old son cast out his line into a massive bait ball swarming around the light. Within minutes he had a bite and caught himself his very first striped bass!!! Within those moments of him having a smile that couldn't be wiped off his face, IllumiSea was born.

We knew we wanted to give others the chance to have a moment like this one. The time as a family that we spend around the light each evening is priceless. Those moments spent together mean so much especially being a military family. Our moments are limited with one another so much, that we have created a family adage. An adage of “collect moments not things”.

We hope that if you choose to purchase a light from us that that one thing you do “collect” will bring you a million moments filled with lasting memories! It sure has for our family of 6!!!
